What is x in 2x − 3 + 4x = 21
2 answers:
Answer: x = 4
Step-by-step explanation:
2x - 3 + 4x = 21
6x - 3 = 21
6x - 3 (+3) = 21 (+3)
6x = 24
24/6
x = 4
So first to rearrange the question so like terms are together
2x + 4x = 21 - 3
Then simplify
6x = 18
Then divide 6 to both sides to find x
X=3
Hope this helps!
